The social media postings of a suspected gunman are a focus of the investigation into Saturday’s fatal shooting at a Pittsburgh synagogue, a federal law enforcement official told CNN.

Robert Bowers, 46, has been identified as the suspect in the shooting that killed multiple people.

Shortly before the shooting, in an account on the Gab social media platform that authorities are investigating, the suspect is believed to have posted he “can’t sit by and watch my people get slaughtered. Screw your optics, I’m going in.”
